The Columbus midi-switcher stands out among its peers with its unique functionality and robust design. Starting at "0" and connecting via XLR to the Herbert or standard MIDI cable to the VH4 and other amps, Columbus draws power via phantom supply from the Herbert or VH4(S). Its bright display ensures visibility even on dimly lit stages, showcasing Diezel's trademark durability. Serving as the ideal companion for Diezel heads, Columbus also functions as the central switching unit for more intricate setups, allowing seamless integration via XLR or MIDI into Diezel heads and beyond. Operating in either Omni-Mode or with selectable channels between 1 and 16, Columbus ships with an external power supply accommodating voltages from 90-240 V AC, making it an essential component for those venturing into the Diezel world or seeking a road-ready midi-switcher for their rig.
